iPhone, Blackberry &amp; Android app

I need an app(or 3!) for iPhone, Android & Blackberry that will search through a user's contacts, find mobile numbers apply some simple criteria and change them in a specific way if they meet the criteria supplied.

The mobile numbers in a users contacts may be in any of the three following formats:

Straight mobile only: eg. 12345678

Mobile number with area code: eg. XX12345678

Mobile number with carrier code & area code: eg. AAAXX12345678

The app will need to ask 2 questions of the user:

Which carrier do you use? This will allow identification of the carrier code

Which Area code are you in? This will allow identification of the area code

The app needs to take this information & change the phone numbers accordingly. All mobile numbers need to have a 9 inserted in front of them.

Straight mobile only: eg. 12345678 becomes 912345678

Mobile number with area code: eg. XX12345678 becomes XX912345678 for one specific area code.

Again, only for a specific area code. If the number is AAAZZ12345678 it doesn't change
